ARTH TASK 14.3

 Create an Ansible Playbook which will dynamically load the variable file named same as OS_name and just by using the variable names we can Configure our target node.( Note: No need to use when keyword here. )

Ansible Facts

Ansible facts are data related to your remote systems, including operating systems, IP addresses, attached filesystems, and more. You can access this data in the ansible_facts variable. By default, you can also access some Ansible facts as top-level variables with the ansible_ prefix.

Lets first check the connectivity:

To see all available facts, add this task to a play:

When we run this small playbook we get all the ansible facts info.... and from this we need to see in which OS our managed node is running and in the ("distribution": "RedHat"), we get the information and further in our ansible playbook we are going to this information

Now, we will use this approach to retrieve the OS name, and with the help of var_files, we are calling the respective OS name yml file which stores the name of the package as we can see below: and from which our software will be installed and run .

Note: The name of the file should be the same as OS-specific name otherwise it will not work!

And here is the playbook:

Now let’s run our playbook :

This will automatically fetch the vars file named RedHat. But how?, {{ ansible_facts[‘distribution’] }} will get replaced with Os name it will replace and since we saved our file with OS name it will replace.
